    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

My first dweet! Tips for working in javascript would be appreciated since I've never used it before

Hey Piggo, to reduce a few chars you don't need var, you can do -- instead of -=1 and you can put some statements in the last term of the from expression, have a look at this that does the same in 116 bytes: Z=Math.abs(T(t/3));for(X=90;X--;)for(Y=90;Y--;x.fillRect(X*10*Z-50,Z*Y*10-50,9,9))x.fillStyle=hsl(${t*150},95%,45%

Hmm the back quotes for removed from the hsl but you get the idea!

Awesome, thanks for the tips!

You've reached the end.
